I'm taking a programming class in which we are learning True Basic. During the last 4 and a half weeks of class, we are going to be working on our FINAL projects. Well, I want to do a simple Mario game for my project. I've already created a horrible pong game, and some other games which involve key input, but no matter how much I experiment with Key Input and Get Key and all that, I can't make it so that the keyboard's repeat delay doesn't interfere. You know in MMF how when you hold a key down, it immediately responds. In True Basic I'm trying to make it so that -- Repeat While "Right Arrow" is Pressed -- Do something... you know what I'm saying? What's a good way to do this in True Basic?
Also, does anybody know of a website which teaches game-making in True Basic? Or are there any platform game engines in True Basic. I need one, cause I really want to make my project good... Is making a game like Mario even POSSIBLE in True Basic? With proper coding, would you actually be able to create platformers. I haven't learned too much of True Basic but I can't find code that allows you to do an equivalent of MMF's "Repeat While Key is Pressed"... So, basically, my questions are:
1. How do I do a proper "Repeat While Key is Pressed" in True Basic?
2. Anybody know of any Mario or platform game engines written in True Basic?
3. Can you load pictures with Transparency in True Basic? I can't find out how...
If it's anything like VB6, you can use the KeyPress instead of GetKey event I believe. I think the GetKey event is used to get the actual ASCII code for the keyboard input at runtime. (ex. The "Enter" Key is ASC Key Code 13)
Equin Village uses this, and the guy will continue to move in the desired direction for as long as you hold the arrow key down, as in MMF's repeat while pressed event.
As for transparency, in VB6 you can't. In order to do it you have to use an API call called BitBlt. Basically, you have to create the actual sprite, and also do a "mask" for said picture that's entirely in black and white. I can't recall exactly HOW to do this, as the API Library call is complicated, but google BitBlt and see what turns up.
Hopefully, the two languages are similar and this helps!

From what I've seen, True Basic's syntax is very similar to that of VB. I'll try the KeyPress and hopefully I'll get transparency to work too. Thanks a lot! Also, anyone know of any websites containing True Basic engines or anything like that? I doubt there are any, but still...
EDIT: I got a basic to True Basic code converter from the True Basic Website, so now I can convert source from Basic to True Basic. Now, the problem is, I want to find the source of a Mario game created in Basic. Anybody know where to find this?
im still using quickbasic . also if true basic is anything like qbasic think if you store the getkey to a variable it runs better.
As for transparencies, i think your talking like seethrough sprites. yes? no? cause i dont think bit blt is for transparecies
in qbasic to do read a sprite thats 10x10 pixels then its mask and place them down to make extra pixels invisible its:
SCREEN 13
DIM sprite(10, 10)
DIM spritemask(10, 10)
FOR y = 1 to 10
FOR x = 1 to 10
READ z
PSET (x, y), z
NEXT: NEXT
GET (0, 0)-(10, 10), sprite
FOR y = 1 to 10
FOR x = 1 to 10
READ z
PSET (x, y), z
NEXT: NEXT
GET (0, 0)-(10, 10), spritemask
PUT((x coord), (y coord)), spritemask, AND
PUT((x coord), (y coord)), sprite, OR

thats a sprite of a rock . it's most likely different for vb6 or true basic so yeah look it up
I'll probably just make the background of my game a solid color so that I don't have to worry about transparency.
Okay, here's another question I have:
I got the Keypress thing to work in True Basic, but it gives me the same result as:
do
if key input then
get key pressed
print pressed
end if
loop
Isn't there a way I can get it just like MMF's "Repeat While Key Is Pressed" condition? So that it detects while a key is down or being held down, and it repeats an event while this is true. Please help!
True! OnKeyDown, change the boolean value to true, OnKeyUp change it to false...
If boolean value is true do the stuff, otherwise not... There you go.. a homemade repeat while key is pressed routine...
Exactly, that's what I was thinking, but how do I do KeyUp and KeyDown in True Basic? I don't think there's a way... But I'll do some more research. Geez, True Basic is getting on my nerves. How the heck do you test for KeyUp KeyDown!!!
Anybody know the syntax for KeyUp/KeyDown for QBasic or Visual Basic? I'll experiment with them and see if I can get it to work in True Basic? At least for QBasic or just plain old Basic, because those languages are the closest to True Basic.
Not sure this is relevant, but try taking a look at http://advsys.net/ken/ . It's the homepage of the guy who made the engine for Duke Nukem 3D. Among other things, already in 1994 he made a 3D engine in Qbasic lots of other cool stuff on there.
A) You shouldn't copy a game idea
B) You shouldn't take someone elses code and say that you wrote it in a programming class
C) You shouldn't be using Basic .
